If you want to use a specific seed in order to get a repeatable random sequence, pass an integer into the constructor:
`javascript`
var generator = new MersenneTwister(123);
and that will always produce the same random sequence.
Also you can do it on existing generator instance:
`javascript``
generator.init_seed(123);
